Byte Size Science took a tour inside the DayGlo Pigment Plant to show how DayGlo makes all of its fluorescent colors. It's pretty fascinating—the color becomes taffy textured and then solidified by cooling and then ground up to be like sand and then ground up again to be between 3-5 microns in diamater. And it's so damn colorful. Like Willy Wonka's Chocolate Factory without the chocolate.

If you're into getting a behind the scenes look of giant fantasy factories and/or appreciate the beauty of tubes, metal, vats, pipes, valves and other industrial things, you should see how the famous fluorescent paint that lights stuff up is made. This is how traffic cones, toys, signs and everything is made. [YouTube]
